According to the Platform Designer user guide, the value for WIDTH_EXPR should be a string representing the name of the parameter (page 701) you want to use (for you "g_adr_width"). You can see an example of this on page 100:

Also, if this doesn't fix the issue, can you show the other commands in your _hw.tcl for the port in question, asi_data_channel_i?
